here is my story first then advice...I had mine removed before I went to Iraq...didnt put me to sleep just used novacaine...all four pulled out which by the way is pretty disgusting to here them crack your teeth and watch them pull out the pieces...my roots were intertwined so the guy yanked on them pulling my head back and forth, however i didnt feel a thing and spent the rest of the day drooling on myself, my wisdoms were all the way in so they didnt need to make any incisions or give me stiches, now for the advice make sure you take your pain killers exactly when your supposed too...if your a little late on the timimg and the pain kicks in, your gunna hate life and second get one of those water piks to keep the holes left in your mouth clean, the last thing you want to end up with is dry socket, makes the pain last longer then the amount of medication they give you. Other then that its really no big deal!
and you really only need to take 3 days off tops, you might still look like a chipmonk from the swelling but the pain dies off after 2 days generally.
